emu48 hp48gx serial calculator connect vspe virtual serial posts emulator - Yellow - 07-28-2020 02:52 PM I use on a windows 10/64 emu48 with a hp 48gx. I'd like to use the hp48g calculator connect software to talk to the emulator. I use vspe - virtial serial ports emulator (latest version). I get transmission errors. Does anyone know why there are errors? What can I do? Is there another method to connect them together? Thanks for your reply RE: emu48 hp48gx serial calculator connect vspe virtual serial posts emulator - rprosperi - 07-28-2020 04:41 PM Check this out, it usually works, though I've not tried it for this exact scenario. http://com0com.sourceforge.net/ RE: emu48 hp48gx serial calculator connect vspe virtual serial posts emulator - Yellow - 07-28-2020 11:34 PM Thankx, It works - Using https://www.virtual-serial-port.org . Virtial Serial Port Driver ver 9.0 build 9.0.575 by Eltima.com The Eltima software tells me that the emu48 uses 9600-N-8-2. And the connectivity kit (HP version2.3 build 2439) uses 9600-N-8-1. It would be nice if one could change it in the EMU48 with the HP 48GX. Or did I missed something in the settings in the HP48GX? I had to deselect the CTS pin in the Eltima software ver 9.0 before it worked. I could not deselect pins in the VSPE software (Eterlogic). Perhaps thats the reason why it did not work? Or has it to do with the difference between the stop bits? I have send them an email and now I'm waiting for an answer.

I don't know what the link has to do on the com0com page. To the 2 Stop bits, the real HP48 use two stop bits, look at https://hp.giesselink.com/Pict/UART/StopBit.htm please. Two stop bits give the receiver more time to handle the received byte.

I don't know what the link has to do on the com0com page. It appears to be a stealthy advertisement for a commercial product. Sad to see sites like Sourceforge and Github (now owned by Microsoft!) sinking to such depths. RE: emu48 hp48gx serial calculator connect vspe virtual serial posts emulator - Yellow - 07-29-2020 11:31 AM The com0com seems to work. https://sourceforge.net/projects/com0com/ Thanks for all your help. |
